Application filed December 3.1, 1908. Serial No. 467,073.

To a whom it may concern Be it known that I, EmiUNn S. CHURCH, a citizen of the United States, residing at Dayton. in the county of Montgomery and State of Ohio, have invented certain new and useful improvements in Tlll'lfi'lilllifi'ifii, of which it declare the following to he a lull, clear and exact description.

This invention rclatesto impn -vements in time printers. more especially to those which are arranged to operate in connection with other machines such as cash registers.

An important consideration in the combination of a time printer and cash register is that the clock mechanism should be as independent as possible from vibrations of among the objects of this invention to attain such desired relation between the two co-acting devices.

A few undesirable featiires found to considerable extent in time printers and which are among the objects of this invention to avoid are, that the type carrying elements are driven directly by the clock mechanism or instead corresponding elements are driven by the clock mechanism, which ele monts control devices for positioning the type-wheels according to the setting of the elements which are positioned by the clock mechanism, but. if neither of these arrangements is employed the clock mechanism sometimes merely controls separate driving mechanism for the type-whcels. The first two have the disadvantage that. the clock mechanism is burdened with the work of' positioning the type-wheels or corresponding elements. making it difficult to regulate the clock when standard clock mechanisms are employed and the clock mechanism is also lia le to harm. through the jarring or vibration of the same when an impression is taken from the type-wheels because of the dircct connection between the type-wheels and the clock. an improvement over the first two. still more or less connects the clock mechanism with the t-ypc vhcols. This arrangement is somewhat objcct ionablc. inasmuch as. clock mechanisn'is are very delicate and have very little surplus power. so that any additional work, and csrwcially any intermittent work requiring a variable amount of energy, is

The last. arrangement while.

l'ia'ving the type-whee ie Wholly independent of the clock mechanism and the setting; of the type-wheels is accomplished by devi s which co-sct with elements waioh rately driven free from the clock mechanism and, the clock mechanism serves to control the driving means for the setting elements.

In one type of time printer which is do scribed in the eo-pending application of 5 K. l assett, Serial No. 341,101 the devi es for setting the type-wheels are arranged so that when an impression 1S IJfl(l8. they wiil move forward and co-act with step d cams which are positioned by the t: mechanism. These devices are arrar pairs, which co-act with pairs 0? stepped cams, so that if onc do of a pair stopped by its respective can: at a certain. position, the other slide wiil n gage its respective cam and come to after traveling; an extentwhich in verse ratio to the extent of movement 0" first mentioned slide. One of the slid; 2. provided with a rack meshing with a p ion which is connectedio the respective typo wheel for said pair of slides. The object. of the above described mechanism is to obtain the differential setting of the type-wheels by means of an invariable stroke of the mining-1' part which carries the pairsof slides and also in the present invention, the prime object of the stepped cams and the pairs of co-aeting slides is for the purpose of convertin; an invariable movement of one part of the machine into a ditierential movement which may be employed to rotate the print: ing wheels desired ext-eats.

In the present machine, the same princi ple of attaining the differential setting of the type-wheels is employed but in a simpler form. namely. each pair of slides are provided with rack teeth and areconnectcd by a pinion meshing with said teeth and one slide is provided with a. set of rack teeth which mesh with a pinion ri id with its respective type-wheel, the same as is do scribed in the before-mentioned patent an plication, but only one of said slices i J ranged to toast with a stepped disk at this "is accomplished in the present invention h angement nrti D in is always 1 than, by 1M Rani. inn: lctbi' inoveinein int!) i i .nied by te use i i merely 911G L iisiz in each of siides.

Theclock mechanism, therefore, merely serves to regulate the rotation of the separately driven escapement wheel. The escapement wheel is so geared to various stepped disks that the minutes disk will move one step each minute, the tens ofminutes one step for each ten minutes, and the hours disk one step for each hour, and the meridian disk one step for each tewe-lve hours. A series of plungers are located in alinement with said disks and when printings are made the plungers are moved toward the disks and are stopped at positions determinedby the particular steps of the disks which are in their paths. The plungers are moved upwardly by means of a shaft which extends across all of the plungers and which is given an invariable reciprocation at each operation of the machine. This shaft is connected to each plunger by pinions which are journaled on the shaft and mesh with rack teeth out in the plungers. Spring resistance is provided normally to prevent rotation of the pinions, but when the plungers have engaged their respective stepped cams or disks, further movement. of the aforesaid reciprocating shaft forces the'pinions to rotate upon the racks of the plungers until the shaft reaches the end of its stroke. A companion rack members is provided foreach of the pl'un-.

gers and meshes with the same pinion but Will be moved extents which are in an inverse ratio to the extents of movement of the plungers, through means of the rotation-of the intermediate pinions after the plunger slides have engaged their respective disks.

.platen is The companion slides mesh with other pinions which are rigid with type-wheels carry ing type for printing the minutes, tens of minutes, etc, according to which of the stepped disks its respective slide is connected.

These type-wheels are mounted at the side of the ordinary amount type-wheels of the cash register, so that when the impression operated a" printing of the time will appear at the side of the slip or check upon As the positioning of the stepped disks is automatically taken care of by the clock mechanism and the mechanism for rotating the said disks, all thatis necessary in order to obtain a printing of the time is to move the shaft which carries the connecting pinions for the pairs of slides toward the stcpped cams a certain invariable distance, so that the plungers which are moved by the said pinions co-act with the stepped disks in a way to effect the desired setting of the type-wheels. The platen is then forced against the type-wheels and the desired impression obtained. 7

Having reference to the drawings, the mechanism of the machine is arranged as vsprings 20 to the escapemcnt'whccl 31.

spring 20.

.is rigidly secured.

follows: Both of the springs 20 and 33 (Figs. 2 and for respectively driving the clock mechanism and the stepped disks are wound from the key shaft 15 which carries a pinion 16 meshing with a gear 17 on the shaft 19 to which the inner ends of the and 33 are are secured. The -gear the usual ratchet 14: and pawl for preventing backward rotation of the springs.

The clock spring 20 as shown in F 1g. 2 rotates the ordinary clock gearing which is merely indicated in said figure by the gear 21, pinion 29. and gears 23and 23 which last are located between the end plates 24 and 25 whichinclose the clock mechanism including the hair spring with its escapement pawl and escapementwheel, etc, as is usual in clocks and is therefore not illustrated in detail; but a shaft -26 of the clock mechanism which makes one rotation during each two minutes is shown provided with an eccentric pin .27 which operates ina slot 28 Fig. 8 in a lever 29 which is securely fastened at its upper pivoted end to an escapement pawl 30, (Fig. 9). Said pawl. co-acts with an 17 carries .escapement wheel 31 to allow the same to move one-half of a tooth space each minute, and as the escapement wheel has thirty teeth it will make one revolution per hour. The escapement wheel is urged to rotate in the direction indicated by the arrow 32, Fig. 9, by the coiled spring 33 (Fig. 2) which through the toothed drum to which one end of the spring is secured, drives the pinion 18 which is rigid on the same shaft with a gear 34 and the gear 34 meshes with a pinoin 35 on a shaft 36 which shaft also carries a pinion or gear 37 (Fig. 3) which ggneshcs with a gear 38, the gear 38 being secured lly following out the gearing so far indicated it may be seen how escapen ent wheel 31 is rotated under the action of the spring 33, the rate of rotation of the escap'cment wheel being controlled by the escapcmcnt pawl 2f) which is rocked by the clock mechzmism-driren by the V The gear 38 is secured to a ratchet wheel 38) which is connected to the minutes disk 40 by the pawl 4i which is mounted upon the minutes disk. The pawl and ratchet connection between the minutes disk 40 and the csrapemcnt wheel 31 allows the minutes disk to be rotated in a'forward direction-i1nlepcndcntly of the cscapcment wheel solhat the same. may be set by rotation of the minutes pointer 42 which is rigidly secured by a thumb nut ii: to the shaft 44 upon which shaft the. minutes disk The minutes disk is of course so geared lo'thu hours and meridian disks that rotation of the same either through the escapcmcnt 31 or the thumb nut 43 will effect the correct corresponding rotation of the disks of higher order and also of the hours pointer 45 which is secured to the sleeve lo surrounding the shaft 44 and upon which sleeve the hours disk 47 is rigidly mounted. The tens of minutes disk 48 is rigidly secured to the minutes disk iO it being unnecessary to gear the two disks together as the steps upon the same arel'so arranged that for each travel of ten steps of the minutes disk the tens-of-minutes disk will travel one step; the steps of course being proportioned in length. The pinion 50 is secured to the minutes and tens of minutes disks so as to rotate therewith and meshes with a gear 51 which is fixed to asleeve 52 upon which is mounted a'pinion 53 which pinion meshes with a gear 54 which isrigid with' the hours disk 4;? and this arrangement of gears aflords-moaement of the hours disk one step for each complete rotation of the minutes and tens of minutes disks. The hours disk is in turn geared to theimeridi an disk 121, to effect the movement of the same one step for each revolution of the hours disk, through the gear 55 which is rigid with the hours disk, and gear 56 which is mounted upon the sleeve 57, which sleeve carries a pinion 58 meshing, through the in termediate pinions 60. and 61,- with the gear 59 which is rigid with the meridian disk.

(Figs. 1 and 3).

From the foregoing description it will be evident that the clock mechanism is limited in function to a control of the stepped disks or graduated elements, and has almost no external" Wei-ii to perform. The energy required to vibrate the escapement lever 29 and eseapement pallet 30 is very small, and the power for turning the graduated elements or stepped disks is derived from an independent spring so that accuracy of the clock mechanism is assured. The stepped disks are all connected together by trains of gearing so that only the minute disk is driven directly from its spring, the other disks being geared in a manner somewhat analogous to that used for-drivin the ordinary hour hand of a clock from t e minutes disk. It will he evident that these disks inst end of being stepped mi 'ht be uniformly circular and provided with printing type, but this construction would be open to the objection previously stated, that 'the clock is liable to derangement by the blow of the printing hamn'ier. To obviate this difficulty the steppeddisks are used merely to position other elements which themselves control the movement of the printing devices, these elements being movable at each operation of the mechanism from'a certain normal position to differential positions depending on the momentary position of the graduated elements.

The shaft (see Fig. 2) upon which the driving gears or pinions 67 are journaled carried. by a. pair of slides 68 and69 which pivotally hung from a bell-crank lever 70 ivoted to the s ide-frame of the machine at 1. The upwardly extending arm'of the bell-crank lever carries a roller 79 which coacts with a groove 73 in a cam disk 74 which is mounted upon a stub-shaft 75. The stubshaft 75 carries a large gear 76 which meshes with a small pinion 77 rigidly mounted upon the main drive shaft 78 of the machine, and

which is iven two rotations upon each operation o the machine, thereby causing the gear 76 to make one-half of a rotation and the groove 73 in the cam 4 is therefore oppositely cut on each side of a center line through the cam so that atevery complete operation of the machine, the hell-crank will be rocked forward and backward.

The gear mechanism, referred to, may be of any desired form, that shown being substantially like the mechanism of Fig. 9 of the Carroll Patent No. 7 54,049, cited, in which the gear 99 thereof-has the same function and general position as the gear 76 in the present case. i The bell-crank carries with it the slides 68 and 69 through which the shaft 65 extends and the upward movement of the pin ions 67 which'are carried by the shaft 65 therefore both causes and permits the plunger slides 80, 81, 82 and 83 to rise assisted by the action of the springs 90 connected to said slides-until the plungers engage their respective stepped disks. During the upward movement of the plungers, the pinions 67 (each of the pinions 67 are made of two segmental halves 84 and 85 of, different radii for the convenience of arrangement of re-.

lat-ed mechanism) roll upon the plunger companion slide racks87 and therefore do not alter the position of the slide racks 8'? but after the plungers engage their respective disks further upward movement of the 4 shaft 65 will cause the pinions 67 to-rotate upon the racks carried by the plunger slides until the supports 68 and 69 for the same reach the end of their stroke; As

statedabove, the pinio'ns 67 are made of two segment-halves 84 and 85 the last of greater diameter than the other; therefore, the pe- .ripheral movement ofthe one side 85 of the pin-ion will be greater than the peripheral movement of the other side of the pinion and as the diameter of the segment-halves are in the ratio of two to one, the movement of the plunger slides is stepped up, to twice the amount at the type-wheels, thus Jpermitting the use of large type on the type-wheels and also making any back-lash between the segment gears and the racks less evident in the alinement of the type-wheels. The two halves of each pinion are pinned together as indicated at 86. When the pinions 67 rotate after their respective plunger slides have come to rest, the'pinions cause a corresponding, movement of their respective racks 87 which mesh with pinions 88 sleeved to the type-wheels 89, and rotate the typewheels according to the extent of rotation of the pinions.

The operation of the difi'erential mechanism just described is as follows: When the slides and 69 are moved upwardly the pinions 37 carry with them their respective plunger slides 80, 81, 82 and 83 which are aided by the springs 90 until the plunger slides engage the stops of the stepped disks which are in their paths, the pinions (l7 meantime merely rolling upon the rack slides 87; but after the plungers have en gaged the stepped disks, the further move ments of the pinions (ST in a vertical direc tion will cause the same to roll upon the plunger slides and therefore lift their respective rack slides 87 and cause the "same to rotate the respective type-wheels to which they are connected, an extent which is in proportion to the distance between the point where their respective plunger slides \vert stopped by the stepped disks and the end of the stroke of the slides (38 and G9. The stops on the stepped disks are arranged so that the stroke of the plunger-sfrom normal position may be divided as follows, that of the minutes plunger slide 80 may be lim ited to any one of nine different parts of the full stroke, likewise plunger slide 81 for the tens of minutes disk may be limited to any one of five parts of its full stroke, plunger slide 99 to any one of eleven parts of its full stroke and plunger slide 83 to merely its initial position or the entire stroke oi the same. The springs 90 may be omitted from the. construction shown as the ditterential mechanism is positive in its operation, and not dependent upon springs 90.

For convenience and accuracy of operation the stepped disks are all positively geared together, as before described, thus contrilniting to simplicity of construction and accuracy of movement. It will be clear, however, that the disks of higher orders, that is, the hour and meridian disks move very slowly, the hours disks being given a complete rotation in twelve hours and the meridian disk a complete rotation in twenty four hours so that the IIIOVQlIlQllt in any one minute of these two disks of higher order will he very small. The result would be that it would be impossible to make the parts accurately enough to provide for unerring setting of the hours and meridian printing wheels from such slow moving graduated elements and that under some conditions a very slight amount of wearing would cause the hours and meridian type- Wheels to be set inaccurately due to a very little back lash in the connectin mechanism for the correspondin graduated elements or to any slight wear tiereof. The construction shown including the positive gearin between the separate orders of graduate elements is of great value, but in order to render it certain in its operation of accurately positioning the type wheels, some additional controlling device for the plungers of higher order should be employed'in order that no small amount of wear or back lash should disturb the accuracy of the mechanism. \Vith this object in view a construction is employed under the control of the minutes graduated element 47, such that the plunger-s for the .higher order elements, that is, the hours and meridian disks are shifted inithe plane of movement of those disks :1} the end of each hour, thereby causing them to be obstructed by the succeeding step of the graduated elements without fai During nearly all of the hour, the higher order plungers move slowly in one direction, thereby more or less keeping pace with the graduated elements'of higher order, but precisely at the end of each hour, the plunare permitted to reverse their shifting movement to a position such that they will unerringly engage the succeeding step of the higher order graduated elements.

A snail cam 92 (see Figs. 6, 9, 2, and 3) rotates with the minutes and tens of minutes disks 40 and 48 and is arranged so that the cut-away part 93 of the same will arrive at the top of a pivoted lever 94 when the disks 40 and 48 have made a complete revolution to their zero position, when the leyer 91 will rock upon its shaft 93 under the action of the spring 96, and the pin 97 which is carried by an arm 98 rigid on the shaft 9.") with the lever 94. will rock out of engagement with a pair of pivoted arms 99 and 100 carried by the hours plunger slide 82 and the meridian plunger slide 83 so that thesaid levers 99 and 100 will be rocked by their springs 101 clear of the points 102 and 103 or 10-i of their respective stepped disks. This construction insures the printing of the correct time if a printing is made just after the minutes disk has passed from 59 to zero, otherwise if the arms 99 and 100 of the plunger slides 82 and 83 were not clear of the points 102 and 103 or 'l04 of their respective stepped disks, the printing would or might indicate one hour less than the correct time.

From this description it will be seen that the object before stated, viz., to cause the printing type-wheels of higher orders to be set nnerringly from the graduated elements having very slow movement, will be cer tainly attained during nearly all of the hour, arm 94 is gradually rocked by cam 92, thereby causing the plunger arms 99 to follow along with the graduated elements and in their planes of movement, while at the end of the hour, the high point of the catyi 92 passes over in front of arm 94, thereby permitting an instant movement of arm 94 and pin 97 so that plunger arms 99 ,are returned to their first position in which they are po-' sitioned to engage the succeeding step of the graduated elements.

'to the type-wheels 89, the minutes plunger slide 80 being connected to the minutes typewheel 105, tens of minutes plunger slide 81 to its respective type-wheel 106, and the hours plunger slide 82 to the type-wheel 107, the meridian plunger slide 83 to the typewheel 108.

The operation of the device is as follows: The type-wheels which are under the control of the keyboard of the cash register are indicated at 110, 111, 112, 113, 114 and 115 (Fig. 1) and the pinions to which they are sleeved are shown at 116. Mechanism for rotating the pinions 116 is omitted from the drawings but the same operates to set the amount type-wheels simultaneously with the setting of the type-wheels which are under the control of the clock. The main drive shaft 7 8 is rotated twice during each operation of the machine. This causes a half revolution of the boxcam 74 which in turn rocks the bell-crank lever upwardly and then returns the same. When the bell-crank lever 7 O is rocked upwardly the plunger slides 80, 81, 82 and 83 are also carried upwardly, through the pinions 67 which are hung from the bell-crank lever 70, until the slides are stopped by their respective stepped disks. Further movement of the bell-crank lever 70 to the end of its full stroke causes the pinions 67 to roll upon the plunger slides an amount which is inversely proportional to the extent of movement of the plunger slides before the same are stopped by their respective disks, and lift the rack slides 87 distances which are in correspondence with the rotation of their respective pinions 67 which rack slides 87 thereby cause rotation of the type-wheels an extent which is determined'by the particular stops of the step ed disks which are in position to be engaged by the plunger slides. At this point the platen 119 and the platen 120 are moved against the-opposite faces of the type-wheels and so cause impressions to be made upon the paper strips 117 and 118. (Fig. 2.) The impressions upon the two strips will be duplicates, as two like sets of type are carried by each of the type-wheels. Further rotat'on of the cam 74 will return the bell-crank l ver 70 to its initial position and thereby return the various plnngers and the type whcels to their initial positions.

From the foregoing complete description, it will be evident that the mechanism is well adapted to attain the objects stated. The

clock is practically free from the necessity of doing external work and thereby will maintain a high degree of accuracy. Any type of time controlled device may be emloyed to perform this function of controling the printing of the time and the invention is not to be limited to what are ordinarily termed clock mechanisms. Any device which is time controlled and serves to permit the periodic actuation of the graduated elements, is considered to be within the invention. The graduated elements are shown as driven by a spring. but this is only one of many forms of driving mechanisms having potential energy stored therein and no other requisite for this mechanism is needed, broadly speaking, than to be constantly tending to drive the graduated elc ments and to be so controlled that it may be periodically permitted to actuate them. The printing elements may take many other forms and in fact, need not to be used to print at all, inasmuch as it is clearly possible to view the wheels, the device then serving as a time indicator, and such time indicator is a differentially movable element and may be positioned in many ways. though the mechanism herein shown in which gears (33 are given an invariable reciprocation in the planes of their rotation is highly satisfactorv in practice. The partial gears 81 and 83 serve to change the invariable reciprocation of the driving devices into a differential movement of the time printer or time indicator.

The mechanism for manually adjusting the graduated elements when necessary is simply providing as it does. a mere connection herein shown as a ratchet and pawl. such that the graduated elements are normally driven by the escapemcut but ma be manually given an additional movmncnt.

lVhile the form of mechanism herein shown and describcd is admirabl adapted to fulfil the objects primarily stated. it i to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed, vfor it is sncoptible of embodiment in various forms all morning within the scope of the claims which follow.
